Accuracy of Digital vs Conventional Denture Impressions: An In Vivo Study

Sponsor: Mohammed Bin Rashid University of Medicine and Health Sciences

View on ClinicalTrials.gov

Summary

The goal of this clinical trial is to compare the accuracy of two denture impression techniques, digital intraoral scanning and conventional border-molded impressions, in adults who have lost all their teeth (fully edentulous patients). The main questions it aims to answer are: Is a digital intraoral scan as accurate as a conventional impression for capturing the shape of the mouth, including movable gum areas? Are repeated digital scans consistent (precise) when taken multiple times on the same patient? Researchers will compare digital impressions taken with an intraoral scanner to conventional impressions made with custom trays and border molding to see if digital scans can match the accuracy of the traditional "gold standard" method. Participants will: Attend Dubai Dental Hospital for two study visits. Have their mouth scanned three times using a digital intraoral scanner. Have a conventional impression taken using a custom tray and high-accuracy material after border molding. Provide informed consent and allow their impression data to be analyzed for accuracy.

PROCEDURE

Digital and conventional impressions

Participants will first receive digital intraoral scanning of their fully edentulous upper and/or lower jaw using the TRIOS 5 intraoral scanner (3Shape). The scanning process follows a structured sequence to capture the entire arch, including the palate and ridge slopes. Each arch will be scanned three times during the same visit to assess precision (consistency of repeated scans). Then the same participants will also undergo a conventional impression procedure using a custom tray and border molding technique.
